i am starting to work in a materialX so can be use in the GPU but the materialsX node are well completely different,

how can i promote a channel? usually, you have the little know on the left side, you can right click it,
or you can make a parameter node and connect that one, and magically that Parmeter will be created in the top level under te UI of that node.

i am missing something.

Hello!

You can manually add it as a relative reference:

super thanks, i was manually going one level up, click the gear > edit parameter interface, add a string channel save it

now "copy channel", and "paste as relative channel" but that to much work have so many channels that i need to promote, is a reason why materialX doesnt have those knobs or right click promote channels?

you can drag parameters directly from inner nodes to edit parameter interface.

i found out if i go to edit parameter interface,
i can look by node, expand and get the parameter i need not the best way but is something
